Hello @phxchris18
Begin by pressing the on button for two seconds and you will get the red colour which is “high”, press again for blue which is “medium”, and again for green which is “low”.
Far Infra-red heat is not as “hot” to the touch as lower vibrational frequencies. However, you can wrap the pad tightly and “preheat” for 20-30 minutes before use and it will feel plenty hot. Make sure you also wrap tightly on your penis for a hotter feel as well. Note after using the temperature of the penis which will be thoroughly heated up as the FIR penetrates deep into the tissues for remodelling go the collagen microstructures
I personally cannot take the high setting as it gets too hot for me when preheated in this way.
